Version 1.2 unstable


  • New Auto-Combat feature! This new combat mode allows the AI the fight with both the player's and the enemy's fleets. An optional 'super fast' mode allows the auto-combat battle to unfold very fast.

  • New 'Fast Combat Animations' speed allows for faster combat sessions. You can toggle between standard and fast speed for animations, and the game keeps that setting until changed again.

  • New 'Hide Future Tech' game option! When going with random tech trees, the player can opt to show all the technologies as of now or to hide all future technologies, which are revealed as the player researches a tech in the previous field.

  • Added a 'Reset queue' option to the Research screen. Allows clearing all techs from the queue.

  • Added a 'Tech re-order' function to the Research screen. Allows re-prioritizing techs in the queue.

  • New Rally Points feature! Allows setting up automated routes for new ships to congregate at a designated star system.

  • New game option to group some of the most frequent and less critical game notifications. Options are: 'Show All', 'Group' or 'Don't Show'. Grouped notifications will present a single notification which can be expanded into its individual notifications, if wished.

  • Now possible to load and save game via mouse double-click.

  • New option to go from the colony screen to the system view screen.

  • Combat bonuses for attacking and defending marines now displayed in space combat boarding operations.

  • New 'Rotate Right / Left' arrow buttons added as an alternative way to using the mouse to rotate a ship in battle.


  • The AI now equips more 'Fighter Bays' and 'Bomber Bays' in their more advanced Orbital Stations (e.g. Battle stations and Star fortresses). Actually, 'Fighter Bays' were not being installed by the AI in Star fortresses due to a bug.
  • The AI players now ask for more or fewer credits from their strategic resources deals depending on their attitude towards the other players and also depending on the game stage (deals more expensive in the late-game).
  • Fixed a bug when the AI attacked lonely orbital stations (no guarding fleets) it would always attack the orbital station even if their objective was to take another settlement in that system, leading to small raids against formidable orbital stations.


  • Defending marines now benefit from a defensive bonus, making a bit harder to board and capture ships now. Defending marines know the ship and can defend it better!
  • Unique powerful technology obtained from the 'Battle Graveyard' event is now obtained a bit later. This super tech could be offered a bit too soon in the game.
  • Space miniaturization effect slightly reduced in the higher levels. The equipment size reduction is now 100-80-65-50-40-33% for no miniaturization to the maximum miniaturization level 5, where before it was 100-80-65-50-35-25%. This will allow installing slightly less low-tech weapons as before, making high-tech weapons even more meaningful.
  • Ion Cannon max damaged now 10, was 12.
  • 'Habitat Control' formula changed to apply diminishing returns for the amount of planetary engineering production available, causing less of an effect on population growth, especially on colonies with more population, with a slight increase in young colonies.


  • Fleet combat auto-resolve improvements: - now factors several key special systems, weapons immunity, much improved missiles and PD weapons calculations and others.
  • Orbital stations now rotate 90 degrees each turn. This will make them a bit tougher.
  • Space monsters not boardable now. It was an unofficial feature till now and not envisaged in the design, and while it could be fun to capture those buggers it was causing many issues as it was not intended to be supported. That said, we have big plans for space monsters going forward.
  • The game now asks if the player wants to use the 'Resilient Settlers' unique ability and colonize planets for which the colonization tech is already available. Before, the ability was automatically used in all planets, since it offered a morale boost, irrespective if the colonization tech was allowed or not.
  • When the player defies the election ruling, all the other AIs now make peace with each other. Before, they only declared war on the defying player, but their current wars were kept going on.
  • Captured orbital stations are now destroyed at the end of the combat. Before, after orbital stations were captured they would still be there in the next turn and had to be fought again.


  • Significant performance boost done to the late game, especially noticeable when playing bigger maps with lots of colonies. Opening and closing the overview panel is much faster, colonizing new worlds and many other functions like closing and opening windows resulting in a much smoother late game experience.
  • Optimizations done to the Swamp and Acid terrains to improve the performance when showing colonies in those terrains.


  • The galaxy map background was brought in closer to the star field and is a bit denser now, allowing for a smoother visualization of the stars that appear to blend better with the background now.
  • Galaxy map planetary and supernova remnant nebulae are a bit dimmer now, allowing them to blend better with the background.
  • The galaxy map star field "corners" were smoothed out a bit to attenuate the "square" feeling, giving it more of a rounder shape.
  • Replaced the Draguul soldier with the proper character and animation (it was displaying an older character from a previous iteration).
  • Tribute deals information is now broken down per empire in the empire treasury tooltip. Displays how much money is paid or obtained, the empires involved and the tribute percentage in question.
  • Added the recommended number of players per map size, viewable in the 'Galaxy Size' tooltip.
  • New 'Number of Players' tooltip in the 'New Game Setup' screen mentions custom races can be created to play games with more than six players.
  • Scrollbars added to the 'Diplomatic Summary' section of the 'Empire Overview' screen to allow listing all treaties with players in the designated area.
  • The colony overview panel now shows a new icon for colonies that happen to have a built orbital station.
  • The Human emperor character is now displayed with better quality, especially in the 'Empire Overview' panel. Also, slight graphical improvements were done to all the characters across the board.
  • All bullet point dashes " - " in tooltips were replaced with bullet points " • ".
  • The Planet construction notification now shows a selection object around the system where the project was finished, highlighting where the planet construction project can take place.
  • Players are now informed when an ongoing 'Planet Construction' project is no longer possible in that system.
  • Combat 'actions' (examples: scan, rotate) were sometimes called 'operations' in the combat UI. This was harmonized and now they are called 'actions' everywhere.
  • Combat 'actions' tooltips were revised to explain the mechanisms better (example: the 'rotate' function usage is now explained better, among others).
  • Combat round number added to the space combat UI next to the "End turn" button.
  • Free ships obtained from events and ruins searching now explain that the SSP (Ship Support Points maintenance) still applies.
  • Ground combat strength value in system view is now rounded. Was showing long decimal value.
  • Outpost labels in the galaxy map are shown a bit brighter to make them easier to see, especially for the darker colors.
  • Technology icons for tech type and associated strategic resources are now also displayed in technologies in the 'Steal Tech' screen when conducting an espionage action. Also, some minor fixes and tweaks to the 'Steal Tech' UI.
  • The 'Economic Capital' production tax bonus is now displayed in the production tooltip as extra money "from Economic Capital" instead of "from Buildings", to make it clear the bonus comes from that empire improvement.
  • 'Available Constructions' renamed to "Construction Projects" in the colony view screen.
  • The color of the colony 'Command Center' building is now associated with the empire color and not the race's default color, as before.


  • Fixed a bug in the galaxy map generation algorithm that was causing the balanced properties of a generated map to be overridden with the wrong number of ideal and tolerable worlds expected for the difficulty setting of choice. This was sometimes causing too few ideal planets to be generated leading to very bad starts near the player, and some AI players, especially in maps with shorter distances between systems and with more players. Now, the correct and expected number of ideal and tolerable worlds is being generated.
  • Fixed a bug in the galaxy map generation algorithm that was causing the players' homeworlds to sometimes be generated too close of each other even if there was a lot of "empty" space left in the map. This was more of an issue in the larger maps, starting at 'Large' size.
  • Fixed a bug on how population growth was being calculated from the 'Habitat Control' eco-engineering project. Total production towards planetary engineering was still being taken into account and used to full effect towards 'Habitat Control' in the same turn a terraforming or another eco-engineering project was finished, leading to more population growth being generated in that turn than it should.
  • Fixed another issue that was causing 'Habitat Control' to not take into account any spilled (overflow) planetary engineering production that could be available from a previously finished eco-engineering or terraforming project.
  • Fixed a bug in the necessary production to develop a planet to infrastructure level 13. The value was set to 11.5 million production required but the correct value is 1.5 million.
  • Fixed a bug in the leader desires to build a wonder, these were not being unfulfilled when the wonder was built by another empire.
  • Fixed a bug that was not allowing the AI to install 'Fighter Bays' on Star fortresses.
  • Fixed a bug in the 'Ship Design' screen that was allowing the 'Fire Arc' weapon modification to be manipulated when the 'Spinal Mount' weapon modification was installed in that weapon slot. With spinal mount, a weapon has a fixed 90 degrees front firing arc.
  • Fixed another bug involving the 'Spinal Mount' modification where the accuracy value in combat could show less than 100% sometimes even though a weapon with the spinal mount modification will always hit.
  • Fixed an issue that was causing the shields animation to always play despite the fact shields were down or the ship was disabled. Now, the shield effect only plays when shields take damage.
  • Fixed a bug that was disabling the weapons overload action after clicking on an enemy ship even if no weapons could reach or were selected to fire against the target.
  • Fixed a glitch in the 'Research screen' where sometimes the strategic resource icons could show a bit outside the tech buttons' designated areas for them.
  • Fixed an issue that was causing the Kaek ships to display a faulty engine trail in combat. The effect was ok in the ship design screen, but not in combat.
  • Fixed a bug when starting a game in 'Gigantic', going to the main menu and starting a game in a 'Small' map would not display the map (map was not centered).
  • Fixed a few dialog text errors and typos.
  • Fixed an issue that was causing an AI request for another AI to make peace with the human player to cause instant peace without informing the player about it. A notification is now sent to the Human player explaining why the peace treaty happened when it is requested by another AI player.
  • Fixed a bug that was allowing the 'Continue' button in the 'Main Menu' screen to become active and pressable after removing the last save from the saves folder, causing the game to freeze when launching.
  • Fixed an issue in the 'Boarding panel' in the combat UI where the number of killed marines could show the previous boarding numbers at the beginning of the next boarding round.
  • Fixed a bug that was causing ships to gain more crew experience than they should in battle encounters involving the Human player and an AI fleet. Fights between AI fleets were not generating this bogus extra XP to be gained.
  • Fixed a UI display bug in the colonies' overview panel where in rare cases a colony could display the gravity value in yellow even when the gravity was ideal to the race in that colony.
  • Fixed an issue that was not allowing the 'R' key to be used to activate / deactivate the 'Rotate' ship action in battle.
  • Fixed a bug when offspring space monsters attacked a system only defended by orbital stations, the creatures would not prompt a fight and just disappeared. Now they attack an orbital station in that system.
  • Fixed an issue in the space combat boarding screen where the combat bonuses for the attacker and defender marines were showing the incorrect number and were not updating properly.
  • Fixed a bug in the boarding capturing calculation which was producing an incorrect value for the chance of an attacking marine killing a defending marine.
  • Fixed an issue in the boarding screen which was showing the incorrect message upon a failed raid. Now shows "Raid attempt failed" where before it would display "Capture attempt failed".
  • Fixed yet another bug on the boarding mechanic that was not allowing combat to proceed when a monster offspring was captured and there were still other monster offspring monsters of that type left in the battlefield.
  • Fixed an issue in the Ambassador leaving diplomatic message. The incorrect generic sentences were being used in some occasions, where now the correct new messages are being displayed depending on the race in question.
  • Fixed a glitch with how some galactic wonder buildings were displayed in the Terran terrain, which could show the wonders as if they were slightly "on air".
  • Fixed a glitch involving the 'Space Elevator' planetary improvement, which could appear in front of the Colony screen 'Close Button' in some terrains and monitor resolutions, not allowing the colony screen to be closed via that button.
